Struct CaseInitiator 

Source 
pub struct CaseInitiator<'a, C>
where
    C: Crypto + 'a,
{ /* private fields */ }
Expand description

CASE Initiator for establishing secure sessions with Matter devices using operational certificates.

This implements the controller side of the CASE protocol. The typical flow is:

  1. Create an exchange to the target device over a plaintext session
  2. Call CaseInitiator::initiate() with the fabric index and peer node ID
  3. On success, the exchange’s session is upgraded to a secure CASE session

Implementations§

Source§

impl<'a, C> CaseInitiator<'a, C>
where C: Crypto + 'a,

Source

pub async fn perform( exchange: Exchange<'_>, crypto: &'a C, fab_idx: NonZero<u8>, peer_node_id: u64, ) -> Result<(), Error>

Perform a CASE handshake with a Matter device.

This performs the complete CASE handshake:

  1. Send Sigma1 (initiator_random, session_id, destination_id, eph_pub_key)
  2. Receive Sigma2 (responder_random, session_id, eph_pub_key, encrypted TBE2)
  3. Send Sigma3 (encrypted TBE3)
  4. Receive StatusReport

On success, a new secure CASE session is established with the target device.

§Arguments
  • exchange - An exchange to the target device over a plaintext session
  • crypto - The crypto implementation
  • fab_idx - The fabric index to use for the handshake
  • peer_node_id - The node ID of the target device
